  • How do I create an 8-bit PNG with transparency from an NSBitmapImageRep?

    - by Rob Keniger
    I have a 32-bit NSBitmapImageRep which has an alpha channel with essentially 1-bit values (the pixels are either on or off). I want to save this bitmap to an 8-bit PNG file with transparency. If I use the -representationUsingType:properties: method of NSBitmapImageRep and pass in NSPNGFileType, a 32-bit PNG is created, which is not what I want. I know that 8-bit PNGs can be read, they open in Preview with no problems, but is it possible to write this type of PNG file using any built-in Mac OS X APIs? I'm happy to drop down to Core Image or even QuickTime if necessary. A cursory examination of the CGImage docs didn't reveal anything obvious. EDIT: I've started a bounty on this question, if someone can provide working source code that takes a 32-bit NSBitmapImageRep and writes a 256-color PNG with 1-bit transparency, it's yours.

  • Are there any drawbacks to using helper :all in Rails

    - by Rob Jones
    In Rails 'helper :all' makes all your helpers 'available' to all your controllers. This is concise and convenient, but does it have any memory and/or performance implications compared to explicitly calling the helpers that each controller actually needs? It's unclear form the docs whether using it involves 'require'ing all those files, or whether autoload is being used. I can't tell from the source in the Rails framework docs. thanks

  • How to pull data from a MySQL column and put it into a single array

    - by Rob
    Basically, this is what I currently use in an included file: $sites[0]['url'] = "http://example0.com"; $sites[1]['url'] = "http://example1.com"; $sites[2]['url'] = "http://example2.com"; $sites[3]['url'] = "http://example3.com"; $sites[4]['url'] = "http://example4.com"; $sites[5]['url'] = "http://example5.com"; And so I output it like so: foreach($sites as $s) But I want to make it easier to manage via a MySQL database. So my question is, how can I make it automatically add additional "$sites[x]['url'] = "http://examplex.com";" and output it appropriately from my MySQL table?

  • Why do C# automatic properties not support default values like VB 2010?

    - by Rob van Groenewoud
    Looking at the new VB 2010 features, I stumbled upon support for Auto-Implemented Properties. Since I'm working with C#, this seemed quite familiar, but I noticed that VB did add a feature I would love to have in C#: setting a arbitrary default value for the auto-implemented property: I really like the clean usage of auto-properties in C#. This would save us the effort of introducing a backing field and hooking it up to the property everytime we simply need a default value, thereby cluttering up the code unnecessarily. I was wondering why this wasn't introduced in C# as well? What could be the rationale for not doing this? Is a syntax discussion going on, or are there technical limitations to implementing this?

  • ASP.NET UpdatePanel > Get selected value from checbox list outside of panel

    - by Rob
    Hi, I have a listing in an UpdatePanel I have some filters for that list in the form a checkboxList control. The checkboxList is created dynamically on page load During the Ajax update (postback), the checkbox list is not populated form the viewstate, so I cannot get the listing to filter. Note: If I put the checkbox list items directly in the markup, it all works, just not if the listing is populated on-postback. protected override void OnLoad(EventArgs e) { if (!Page.IsPostBack) { foreach (var p in global.Product) CheckListManufacurer.Items.Add(new ListItem(p, p)); } base.OnLoad(e); } <form id="ProductListForm" runat="server"> <asp:ScriptManager ID="ScriptManager" runat="server" EnablePartialRendering="true"></asp:ScriptManager> <asp:CheckBoxList ID="CheckListManufacurer" runat="server" EnableViewState="true"> <asp:ListItem Value="" Text="(All)"></asp:ListItem> </asp:CheckBoxList> <asp:Button id="btnTestAjax" runat="server" Text="Test" /> <asp:UpdatePanel ID="ProductsPanel" runat="server" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnTestAjax" /> <asp:AsyncPostBackTrigger ControlID="CheckListManufacurer" /> </Triggers> <ContentTemplate> <sr:ProductList ID="Products" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </form>

  • VB.NET function that takes other functions as a parameter, and executes them

    - by rob
    Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

  • C# compiler error CS0006: metadata file is not found

    - by Rob
    I've built a c# compiler using the tutorial on MSDN and a few other resources including here, and I've gotten it to work until I add additional reference assemblies. My errors stem from adding "System.dll" and "System.Windows.Forms.dll" to the ReferenceAssemblies list. here's my code: private void SetUpCompilingParameters() { string ver = string.Format("{0}.{1}.{2}", Environment.Version.Major, Environment.Version.MajorRevision, Environment.Version.Build); string libDir = string.Format(@"{0}", Environment.CurrentDirectory); string raDir = @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0"; string exWpfDir = string.Format(@"C:\WINDOWS\Microsoft.NET\Framework\v{0}\WPF", ver); string exDir = string.Format(@"C:\WINDOWS\Microsoft.NET\Framework\v{0}", ver); MyCompiler = new CSharpCodeProvider(); CompilingParam = new CompilerParameters(); CompilingParam.GenerateExecutable = false; CompilingParam.GenerateInMemory = true; CompilingParam.IncludeDebugInformation = false; CompilingParam.TreatWarningsAsErrors = false; CompilingParam.CompilerOptions = string.Format("/lib:{0}", libDir); CompilingParam.CompilerOptions = string.Format("/lib:{0}", raDir); CompilingParam.CompilerOptions = string.Format("/lib:{0}", exDir); //CompilingParam.CompilerOptions = string.Format("/lib:{0}", exWpfDir); CompilingParam.ReferencedAssemblies.Add("System.dll"); CompilingParam.ReferencedAssemblies.Add("System.Windows.Forms.dll"); } As you can see, I've explicitly referenced directories in CompilerOptions but its not helping. I'd like to test the solution on here on stackoverflow that utilizes: CompilingParam.ReferencedAssemblies.Add(typeof(System.Xml.Linq.Extensions).Assembly.Location); but I'm having trouble using it for the general System.dll etc...

  • problem running system.net.webclient and process.start off a control event

    - by Rob
    The following code causes my vs 2008 wpf project to hang, I'm not sure why. Both Part 1 and Part 2 work perfectly fine independently, but when I run them together on an control event (click a button for example) the program hangs. I've also tried shell execute for part 2 - same results. However, this code when run within the form loaded event works fine. Any insights would be truly appreciated. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click 'Part 1 Dim myWebClient As System.Net.WebClient = New System.Net.WebClient Dim CurrentDataFileContents As String = myWebClient.DownloadString("http://www.xyz.com") myWebClient.Dispose() 'Part 2 System.Diagnostics.Process.Start("http://www.test.com") End Sub

  • C++ 'mutable' keyword

    - by Rob
    A while ago I came across some code that marked a member variable of a class with the 'mutable' keyword. As far as I can see it simply allows you to modify a variable in a 'const' method: class Foo { private: mutable bool done_; public: void doSomething() const { ...; done_ = true; } }; Is this the only use of this keyword or is there more to it than meets the eye? I have since used this technique in a class, marking a boost::mutex as mutable allowing const functions to lock it for thread-safety reasons, but, to be honest, it feels like a bit of a hack.

  • VS2010 always relinks the project

    - by Rob Walker
    I am migrating a complex mixed C++/.NET solution from VS2008 to VS2010. The upgraded solution works in VS2010, but the build system is always refereshing one C++/CLI assembly. It doesn't recompile anything, but the linker touches the file. The causes a ripple effect downstream in the build as a whole bunch of dependent then get rebuilt. Any ideas on how to find out why it thinks it needs to relink the file? I've turned on verbose build logging, but nothing stands out.

  • Alternative to Microsoft Agent / Fix for color issue?

    - by Rob P.
    I've got an app that does Text-To-Speech; but I wanted to show an animated face/character to go with it. I found a tutorial on Microsoft Agent and I implemented it in my vb.net app. The problem is with the transparency color. Unless I run application in compatibility mode/256 colors, the characters will appear with a purplish-pink background image instead of a transparent back-color. But running the app in 256 colors the rest of the app looks awfully out of place. First - is there something that works similar to MS Agent I can use that would be more appropriate? Second - if I'm still MS Agent - can I get the transparent color to work correctly without limiting myself to 256 colors?

  • xval get message from resource file

    - by Rob
    I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this? Below the code which should make the relation to the resourcefile en specify the error when the field is left empty. [Property] [Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")] public virtual Double ShippingCost { get; set; }

  • Which single IoC/DI container would you recommend using and why?

    - by Rob G
    I'm asking this question because it's a good way to gauge how the community at large feels about the various containers/frameworks and why. Also, whilst my expertise may lie in .Net development, I am very interested in which frameworks are popular (and why) in other languages. If I feel the need to start digging into Java for instance, then I'd like to hit the ground running with good (comfortable) knowledge that I'm starting in the right direction. Does Ruby even need one with all its magnificent dynamicism? I have my own opinions on the .Net front, and will probably add my own personal favourite in an answer below, but I'm interested in all languages and opinions here. With all that in mind, could you please state only one IoC/DI framework that you use and recommend with the language of choice (Java/Ruby/.Net/Smalltalk etc.) and your reasoning for your choice, and if someone has already answered your particular flavour, then you can just vote it up and add comments to it so that anyone looking for advice in future and see which frameworks are more than likely to work for them once they read your reasoning. I'm hoping that over time, the best ones will bubble up to the top. I realise that this question doesn't have only one correct answer, so I won't be choosing one - the community will decide which framework gets the most votes and why. Of course, if you really feel strongly opposed to a particular brand, you could take the reputation hit and vote it down too, and this question can serve as a true wiki-style entry for research into this field. Remember, only one IoC per answer you write please - if you feel the need to promote two frameworks, then write two answers with your reasoning inside for each choice - then others in the community can agree or disagree with you.

  • UIPickerView issues - iphone

    - by Rob J
    I have the following: - (NSInteger) numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 2; } - (NSInteger) pickerView:(UIPickerView *) pickerView numberOfRowsInComponent:(NSInteger) component { return [genderPickerData count]; return [agePickerData count]; } When I do this, the UIPicker is split into 2 components, but the PickerData is only being represented for gender on both pickers. I am trying to figure out through Apple's confusing documentation on how I reference each individual component but can't seem to figure it out.

  • Creating a custom Configuration

    - by Rob
    I created a customer configuration class Reports. I then created another class called "ReportsCollection". When I try and do the "ConfigurationManager.GetSection()", it doesn't populate my collection variable. Can anyone see any mistakes in my code? Here is the collection class: public class ReportsCollection : ConfigurationElementCollection { public ReportsCollection() { } protected override ConfigurationElement CreateNewElement() { throw new NotImplementedException(); } protected override ConfigurationElement CreateNewElement(string elementName) { return base.CreateNewElement(elementName); } protected override object GetElementKey(ConfigurationElement element) { throw new NotImplementedException(); } public Report this[int index] { get { return (Report)BaseGet(index); } } } Here is the reports class: public class Report : ConfigurationSection { [ConfigurationProperty("reportName", IsRequired = true)] public string ReportName { get { return (string)this["reportName"]; } //set { this["reportName"] = value; } } [ConfigurationProperty("storedProcedures", IsRequired = true)] public StoredProceduresCollection StoredProcedures { get { return (StoredProceduresCollection)this["storedProcedures"]; } } [ConfigurationProperty("parameters", IsRequired = false)] public ParametersCollection Parameters { get { return (ParametersCollection)this["parameters"]; } } [ConfigurationProperty("saveLocation", IsRequired = true)] public string SaveLocation { get { return (string)this["saveLocation"]; } } [ConfigurationProperty("recipients", IsRequired = true)] public RecipientsCollection Recipients { get { return (RecipientsCollection)this["recipients"]; } } } public class StoredProcedure : ConfigurationElement { [ConfigurationProperty("storedProcedureName", IsRequired = true)] public string StoredProcedureName { get { return (string)this["storedProcedureName"]; } } } public class StoredProceduresCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { throw new NotImplementedException(); } protected override ConfigurationElement CreateNewElement(string elementName) { return base.CreateNewElement(elementName); } protected override object GetElementKey(ConfigurationElement element) { throw new NotImplementedException(); } public StoredProcedure this[int index] { get { return (StoredProcedure)base.BaseGet(index); } } } } And here is the very straight-forward code to create the variable: ReportsCollection reportsCollection = (ReportsCollection) System.Configuration.ConfigurationManager.GetSection("ReportGroup");

  • iPhone code to create new NSUserDefaults objects?

    - by Rob
    I have NSUserDefaults storing a number of string variables for things like name, date of birth, address, etc. What I would like to know is how to write a code that will create a new object for each new user. For example, I have a spinning wheel that shows up immediately after the first time the user runs the app. What I want, is for that wheel to have one single option - "New User". Once that New User fills out a bunch of text fields that I am using NSUserDefaults to save, I want that user to be saved on that spinning wheel so that the next time they open up the app they have the option of returning to all of the variables that they previously put in, or creating a new user so they can input all new variables. I know how to do everything except write the code to create new users automatically. Potentially, the program should allow for a limitless number of these user objects and then just use something arbitrary like their last name to input into the spinning wheel. I would assume that the code would need to be put somewhere in the following code used to save the NSUserDefaults: NSUserDefaults *userData = [NSUserDefaults standardUserDefaults]; [userData setObject:txtName.text forKey:@"name"];

  • Using ViewModels in ASP.NET MVC 2 - multiple forms

    I couldn't find any documentation around using multiple forms in an ASP.NET MVC 2 ViewModel approach. i.e. In the built in application when you select New MVC2 web app, the register page uses a ViewPage which inherits like this:- Inherits="System.Web.Mvc.ViewPage" I wanted to use that approach on a page with multiple forms, but that RegisterModel only supported one form.

  • jQuery error when aborting an ajax call only in Internet Explorer

    - by Rob Crowell
    When mousing over an image in a jcarousel, my site displays a popup whose contents are loaded via ajax. I'm doing what I thought was fairly straightforward; keeping a handle to the xhrRequest object, and aborting the existing one before making a new request. It works great in all browsers except IE, where I receive an error "Object doesn't support this property or method" Here's the code that is triggering it: function showPopup { // ... code snipped ... // cancel the existing xhr request if (showPopup.xhrRequest != null) { showPopup.xhrRequest.abort(); showPopup.xhrRequest = null; } showPopup.xhrRequest = $.ajax({url: url, type: "GET", success:function(data) { $("#popup-content").html(data); } }); // ... code snipped ... } showPopup.xhrRequest = null; Works great in Firefox and Chrome. I traced the error down to this bit of code in jquery.js inside the ajax function (line 5233 in my copy of jQuery): // Override the abort handler, if we can (IE doesn't allow it, but that's OK) // Opera doesn't fire onreadystatechange at all on abort try { var oldAbort = xhr.abort; xhr.abort = function() { if (xhr ) { oldAbort.call( xhr ); } onreadystatechange( "abort" ); } catch(e) { } The specific error occurs on the oldAbort.call( xhr ) line. Any ideas?

  • Using Bundler along with preinstalled gems

    - by Rob Cameron
    So I've got thin installed the old fashioned way: gem install thin I put an app on the server and installed all of its required gems via bundler: bundle install But, when I tried to start the app with thin start, it can't find any of the bundler-installed gems since they're not installed in the default gems directory. My question is: how do I make this work? Do I need to install thin via bundler as well? Will that still set up the thin executable in /usr/bin so I can start it from the command line like normal? Thanks!

  • Apache - Reverse Proxy and HTTP 302 status messsage

    - by Rob
    My team is trying to setup an Apache reverse proxy from a customer's site into one of our web applications. http://www.example.com/app1/some-path maps to http://internal1.example.com/some-path Inside our application we use struts and have redirect = true set on certain actions in order to provide certain functionality. The 302 status messages from these re-directs cause the user to break out of the proxy resulting in an error page for the end user. HTTP/1.1 302 Found Location: http://internal.example.com/some-path/redirect Is there any way to setup the reverse proxy in apache so that the redirects work correctly? http://www.example.com/app1/some-path/redirect
